Armbury Hardy SG Screw-Gate HMS Carabiner

Armbury Hardy SG Screw-Gate HMS Carabiner

The Armbury Hardy SG is a large, pear-shaped HMS carabiner with a screw-lock gate for mountaineering and work at height. Its roomy basket accommodates a Münter hitch or belay device, while the keylock nose helps reduce snagging during handling.

Room to work, details that matter

At the belay station or on a working-at-height system, the Hardy SG gives you a generous 26 mm gate opening and an ergonomic shape that is easy to handle. A red indicator makes an unlocked gate easier to spot, and the hot-forged I-beam construction balances size, strength and weight.
